Title: Substrate processing method and processing liquid
Inventor: SASAKI YUTA
IPC: H01L21/302
Filed: 2022-04-15
Abstract: The present invention pertains to a substrate processing method and a processing liquid. An upper surface W1 of a substrate W includes: a pattern formation region W1a on which patterns P are formed; and a pattern non-formation region W1b on which the patterns P are not formed. This substrate processing method includes a processing liquid supply step, a solidified film formation step, a sublimation step, and a removal step. In the processing liquid supply step, a liquid film H made of a processing liquid is formed on the upper surface W1 of the substrate W. The processing liquid contains a sublimable substance and a solvent. In the solidified film formation step, the solvent is evaporated from the liquid film H to form a solidified film K containing the sublimable substance on the upper surface W1 of the substrate W. The solidified film K has: a first solidified film Ka positioned on the pattern formation region W1a; and a second solidified film Kb positioned on the pattern non-formation region W1b. In the sublimation step, the first solidified film Ka is sublimated. In the removal step, the second solidified film Kb is removed from the substrate W.
